Description: Manages Power over Ethernet (PoE) on Extreme Networks switches, monitoring power sourcing equipment status, power consumption, and per-port PoE settings.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is EXTREME-POE-MIB?

EXTREME-POE-MIB is an Extreme Networks proprietary MIB for managing Power over Ethernet (PoE) on Extreme enterprise switches, part of the wired LAN switching technology area. It exposes system-wide PoE configuration (admin enable, disconnect precedence, usage threshold, power-supply mode, legacy device support) and per-slot power-sourcing-equipment (PSE) data including power limits and consumed power for switches with modular PoE slots. It is explicitly useful for monitoring hardware status: power supply mode and per-slot power limit versus actual consumption reveal whether a switch chassis is nearing its PoE power budget, which threatens the ability to power additional PoE devices like phones, cameras, or access points. It is a vendor-specific extension typically deployed alongside the standard IETF POWER-ETHERNET-MIB (RFC 3621) for base per-port PoE status, and administrators performing an EXTREME-POE-MIB download from Extreme Networks' support site would compile it together with that standard MIB for complete PoE visibility. It is deployed on Extreme Networks modular/stackable switches in campus/enterprise networks powering PoE endpoints.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-POE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Extreme Networks 5420 Series switch — universal switch with 802.3bt 30/60/90W PoE
  • Extreme Networks 4000 Series — 90W PoE, multi-gigabit access switch

Monitoring Examples

An administrator would poll extremePethSlotConsumptionPower against extremePethSlotPowerLimit per extremePethPseSlotEntry (indexed by extremePethSlotNumber) to see how much of a slot's PoE power budget is in use, and check extremePethSystemUsageThreshold to know when a warning trap fires. If extremePethSystemPowerSupplyMode indicates a redundant/degraded power supply, or extremePethSlotConsumptionPower approaches extremePethSlotPowerLimit, PoE devices on that slot risk being denied power or disconnected per extremePethSystemDisconnectPrecedence.

What Can Be Monitored

  • PoE system admin enable state
  • per-slot PoE power limit
  • per-slot PoE power consumption
  • power supply mode/redundancy
  • PoE usage threshold
  • legacy PoE device support enable
